[PATCH v2 0/6] Various fixes and improvements to initscripts

[Ben Shelton]

This patch series contains fixes and improvements we've made to several init 
scripts.  These changes have been thoroughly tested on Dylan and ported to 
master.

Changes made in v2:
  - Updated /etc/timestamp generated at build time to use seconds accuracy
  - Added a patch I missed the first time to source /etc/default/urandom 
    from /etc/init.d/urandom

The following changes since commit a449598a839e677e2a094aa4bd9a68003de6e42e:

  bdwgc: Add PACKAGECONFIG for libatomic-ops (2014-07-17 15:04:07 +0100)

[PATCH v2 1/6] initscripts: bootmisc.sh: Make sysctl -p honor VERBOSE

[Ben Shelton]

From: Richard Tollerton <rich.tollerton@ni.com>

busybox sysctl may lack the "-q" setting, so simulate it with redirects.

[PATCH v2 2/6] initscripts: save /etc/timestamp with seconds accuracy

[Ben Shelton]

From: Blair Elliott <blair.elliott@ni.com>

Currently, /etc/timestamp is saved with minutes accuracy.  To increase
the accuracy, modify the save-rtc.sh and bootmisc.sh scripts to save and
read /etc/timestamp respectively with seconds accuracy.

[PATCH v2 3/6] initscripts: parametrize random seed file location

[Ben Shelton]

From: Richard Tollerton <rich.tollerton@ni.com>

Currently, the random seed file location is hardcoded to
/var/lib/urandom/random-seed.  Refactor it to a parameter
(RANDOM_SEED_FILE) so the file location is defined in only one place.

[PATCH v2 4/6] initscripts: Use current date as an additional source of entropy

[Ben Shelton]

From: Ken Sharp <ken.sharp@ni.com>

If the seed file is empty or does not exist, the date is an extremely
poor backup source of entropy, but it is better than nothing.

[PATCH v2 5/6] initscripts: make hostname.sh coreutils-compatible

[Ben Shelton]

From: Richard Tollerton <rich.tollerton@ni.com>

inetutils and busybox hostname utils support `hostname -F`; coreutils
hostname doesn't. So just use `cat` instead.

[PATCH v2 6/6] initscripts: Add support for /etc/default/urandom

[Ben Shelton]

From: Richard Tollerton <rich.tollerton@ni.com>

Source /etc/default/urandom if present.  This allows the rootfs to
remain read-only while enabling the user to override the location of the
random seed file.

The syntax above doesn't appear to work with busybox:

/etc/init.d/rc: /etc/rcS.d/S55bootmisc.sh: line 73: syntax error: bad substitution 

:(

Cheers,
